Motion analysis of flagellar bacteria

Nanotechnology finds in flagellar bacteria an uncomparable example of a very efficient and miniaturized motor. This and the complex behavior of the bacteria colonies growth in a self-organized way make the study of flagellar bacteria very important and appealing for possible applications. For these reasons in this work single bacterium motion and colonies growth have been studied by applying nonlinear methods. The characterization of the single bacterium motion leads to the conclusion that determinism (due to chemotaxis) is predominant with respect to random terms. This result is confirmed by the possibility of modelling the case study of colonies growth through an activation/inhibition dynamics.
